# Shell script to emulate Silicon Graphics install program.
# We emulate the non-standard interface used by install so
# that we can build SGI inst packages on SGI systems.  Note
# that we cannot emulate everything because we don't maintain
# a history of installed software; thus we cannot tell when
# configuration files have been modified and save old copies.
#
# NB: we don't do chown/chmod/chgrp by default; it must be
#     explicitly set on the command line.
#

#
# install [options] files ...
# 
# Options are:
#
# -o		save existing target foo as OLDfoo
# -O		remove existing target foo, if it fails save as OLDfoo
# -m mode	set mode of installed target
# -u uid	set uid of installed target
# -g gid	set gid of installed target
# -root path	set ROOT directory for target pathnames
# -dir		create directories
# -fifo		create FIFO special files
# -ln path	create hard link
# -lns path	create symbolic link
# -src path	source pathname different from target
# -f dir	install files in the target directory ROOT/dir
# -F dir	like -f, but create directories that do not exist
# -v		echo actions
# -idb stuff	specify package and, optionally, do special work
